Connect Adyen to Generic MCP Clients

Connect any stdio-compatible MCP client to local KosmoKrator integration tools.

Register kosmo mcp:serve as the command for a local stdio MCP server. The gateway is local, scoped to this integration, and starts with --write=deny so MCP clients can inspect read-capable tools without receiving write access by default.

Adyen MCP Config for Generic MCP Clients

Start with read-only write policy and expand only for trusted projects.
